This post was updated November 30, 2012 to reflect the additional availability of PHP 5.2.17.
We currently offer PHP versions 5.2.6, 5.2.17, and the 5.3 series. You can choose which version your account uses in the “PHP Settings” section of our “My Account” control panel.
PHP 5.2 has been obsolete for many years. Because of that, we’re beginning the process of removing PHP 5.2.6 from our servers and encouraging customers to switch to PHP 5.3. (PHP 5.2.17 is still available for now, but discouraged.)

Shortly after we made PHP 5.3.15 available to hosting customers, the PHP team announced the release of version 5.3.16 that fixes several bugs.
We’ve upgraded PHP 5.3.15 to PHP 5.3.16 on our servers as a result.
PHP 5.3.15 is now available on all hosting accounts. It’s the default for new customers, and existing customers can update their PHP version using the “PHP Settings” link in our “My Account” control panel.
If you’re an existing customer using an older version of PHP, we haven’t yet changed your PHP version. However, we will begin doing that in about 30 days (we’ll announce that separately), so we recommend that you upgrade now. That way, if you find you’re using an outdated PHP script that isn’t compatible, you can set PHP back to the previous version and work to update the script. The old PHP 5.2 series will be removed from our servers by the end of 2012.

Within the next few weeks, we’ll be making PHP version 5.3.15 available to customers in our account management control panel (and making the 5.3 series the default for all customers several months after that).
We’ve been testing PHP 5.3 ourselves for some time (among other things, it’s been running our Webmail system for several weeks, handling millions of page views without any problems), but it makes sense to test it on a wider variety of sites before deploying it for everyone.
If you would like to help us test PHP 5.3, just contact us and let us know what site(s) you’d like to enable it for. We’ll do that for you (it needs to be done manually by our staff for now).

There’s been a lot of talk in the last few days about a nasty PHP security bug that allows “hackers” to compromise some Web sites that use the PHP scripting language.
Our customers are not vulnerable to this problem because of the way PHP is set up on our servers. You don’t need to worry about it.

We’ve installed a PHP 5 security update. Customers should not notice any changes; the update just fixes several security issues in PHP 5.
After upgrading our systems to PHP 5.2.6, we received reports of an incompatibility with Joomla. Some URLs do not work when Joomla is configured to use “Search Engine Friendly URLs”, but to not have “Use Apache mod_rewrite” turned on.
We’ve investigated this, and it’s caused by Joomla assuming that PHP has a bug that makes it work incorrectly, when in fact it’s supposed to work differently (and is clearly documented to work differently). Older versions of PHP had this bug, but the new version doesn’t.
To help our customers work around this, we’ve “patched” PHP to intentionally reintroduce the old bug for now, thus keeping it “compatible” with Joomla. If you were having trouble with Joomla’s “Search Engine Friendly URLs”, it should be fixed.
We’ll provide more technical details (and a more robust long-term solution) in the near future.
Update: We’ve also reported this problem to the Joomla developers and suggested a solution.
For the last several years, we’ve offered PHP versions 4 and 5 on our servers. This made sense when PHP 5 was new: Even though PHP 5 is faster and more secure than PHP 4, a small handful of scripts were originally incompatible with version 5, and we wanted to give customers a choice.
However, PHP 5 is now more than five years old, and the PHP developers declared version 4 obsolete in 2007. All our new customers have been using PHP 5 by default for more than a year, and we’ve received no complaints about incompatibilities.
No PHP script should require the obsolete PHP version 4 any more. Because of that, we’re beginning the process of removing it from our servers.

We’ve installed a PHP 5 security update. Customers should not notice any changes; the updates just fix several security issues in PHP 5.
We’ve installed MySQL and PHP 5 security updates. Customers should not notice any changes; the updates just fix several security issues in PHP 5 and MySQL.
The updates were performed in such a way that new Web server connections were delayed during the 30 seconds or so that PHP and MySQL were unavailable on each server. That should mean that as far as scripts on your Web site were concerned, there was zero downtime.
